This lousy problem has taken over my life! :-(

I don't know what it is, but I hate it when I think
I know something and I don't. (I don't mind being dumb,
but I don't like to be stupid.) So, because I thought
this was a simple problem, I got most annoyed when
my simple solutions wouldn't work with it. And when
I get annoyed, I do tend to get a little over-the-top
tenacious.

But, as with so much in life, there is always more to learn.
I *finally* figured out how to do this in a simple way.
I know a little bit more about this now then I knew a couple
of days ago. And the price I paid to gain this knowledge was
pretty dear, so I'm not likely to forget it. That's a plus,
too, I guess.

Anyway, I wrote an article about this in case anyone else
wants to avoid banging their head against a wall. :-)

And a special thanks to Garrison Keillor and Ana Ivanovic
for inspiration. And, of course, to Roman and to all the
others on this newsgroup whose simple questions are sometimes
the hardest to answer.

Cheers,

David
